bin: add fix-home-db.sh — direct SQLite seed for HomeSection table

The Jellyfin 10.10.3 REST endpoint won't INSERT HomeSection rows for the
'Jellyfin Web' client (only updates existing rows), so users whose web-
client DisplayPreferences was created without explicit home-section state
fall back to factory defaults that include Next Up. Applying CustomPrefs
via API doesn't help — the web client reads HomeSection rows.

Direct DB seed: for every DisplayPreferences row with zero HomeSection
rows, insert [Resume, LatestMedia, None*8]. Also replace Type=7 (NextUp)
with Type=0 (None) across all DPs. Idempotent.

+# Direct SQLite fix for Jellyfin 10.10.3 home-screen sections.
+#
+# Why this exists:
+#   The REST endpoint `POST /DisplayPreferences/usersettings?client=Jellyfin Web`
+#   updates `DisplayPreferences.CustomPrefs` but does NOT insert into the
+#   `HomeSection` table for that client (it only inserts when called with
+#   client="emby"). The web client reads from `HomeSection` rows on the
+#   `Jellyfin Web` DisplayPreferences row, so the legacy POST has no
+#   visible effect until those rows exist.
+#
+# What this script does (idempotent):
+#   1. Insert a `Jellyfin Web` DisplayPreferences row for any user missing one.
+#   2. Seed canonical home layout [Resume, LatestMedia, None*8] for every
+#      DisplayPreferences row that has zero HomeSection rows.
+#   3. Replace any Type=7 (NextUp) with Type=0 (None) across the table.
+#
+# Type integers (Jellyfin.Data.Enums.HomeSectionType):
+#   0=None, 1=SmallLibraryTiles, 2=LibraryButtons, 3=ActiveRecordings,
+#   4=Resume, 5=ResumeAudio, 6=LatestMedia, 7=NextUp, 8=LiveTv, 9=ResumeBook
+#
+# Container must be stopped during write to avoid corrupting the EF Core
+# WAL. After write, restart the container.
+#
+# Usage:
+#   docker stop jellyfin
+#   DB=/home/docker/jellyfin/config/data/jellyfin.db bin/fix-home-db.sh
+#   docker start jellyfin
